New Appendix in Manual pdf
by Andrea paz 18 Jul '20

18 Jul '20

I wanted to ask for an opinion on a couple of new things that I have introduced in the manual (but going back is easy; that's why I ask for advice): 1. The nice pdf tutorial of fary54 I put it in a new section of the appendix, both because it is 4 pages long, but above all to give it more importance and accessibility. What do you think about it? Is it better to put it back in the body of the manual, in the corresponding section? 2. Also, in the fary54 tutorial I put links to his videos that illustrate some passages. These videos are uploaded in our Youtube channel, but they are not visible to the public. Thanks to Sam's idea, they are put as "unlisted" and can be seen only by following the link put on the manual. They're not real tutorials, they're simply the analog of the videos that we sometimes put on streamable to make new users understand how some tools work. Do you like the idea of integrating the manual with explanatory video links or is it better to keep Manual and videos separate? Note: if you want to contribute, describing the type of workflow you use in your daily editing work, it would be a valuable addition to the manual. I personally would like to know how to do audio editing (sync, audio in different tracks, sound mixing, etc), since I'm totally ignorant about it.

UPD: Offtop: "Spp2Pgs - Converts general subtitles to HDMV PG streams"
by Andrew Randrianasulu 14 Jul '20

And of course I found something related to VCXPROJ->Cmake conversion minutes after I send this email out! https://pypi.org/project/cmake-converter/ written in Python3, tries to autoconvert c/c++/fortran projects ... Last version is 2.0.1 from 10 Dec, 2019 (so, not abandoned) Interesting, it may not work for big projects with GUI, but hopefully for small command line tools like this (lib)spp2pgs .... ---------- Пересланное сообщение ---------- Тема: Offtop: "Spp2Pgs - Converts general subtitles to HDMV PG streams" Дата: Вторник 14 июля 2020 Отправитель: Andrew Randrianasulu <randrianasulu(a)gmail.com> Получатель: "Cinelerra.GG" <cin(a)lists.cinelerra-gg.org>, Marton Balint <cus(a)passwd.hu>, "Cinelerra.GG" <cin(a)lists.cinelerra-gg.org> So, I was doing another pass at 'what exactly can encode those PGS streams?' and found this little project: https://github.com/subelf/Spp2Pgs --desc---- Spp2Pgs Converts general subtitles to HDMV PG streams. In other words, converts .ass files to .sup files. The project generates a command line application and a CLR dll file. Core of them is a static library, libspp2pgs. An external dll, xy-VSSppf, is introduced to deal with subtitle files. It's based on a forked version of xy-VSFilter, rendering and providing subtitles in a more easy way. Here is a breif description for all the four parts. Spp2Pgs*.exe An executable converts subtitles to .sup files. Usage: Spp2Pgs -i "X:\Saya1011con.ass" -s 1080 -r 23 "X:\Saya1011con.sup" Type Spp2Pgs -h for more help. libspp2pgs & Spp2PgsNet*.dll The core and its CLR library wrapper for .NET framework applications. Three classes play the main role: PgsEncoder, encoding and writing a pgs file. FrameStream, reading subtitles and rendering subtitles into image. Spp2Pgs, an entrance for all other things. Also reading images from FrameStream and sending them to PgsEncoder. --- It seems to be Windows-based (at least build files are *.vcxproj), and has some x86 asm (yasm) functions, but better than nothing, I guess ...

Slightly updated russian translation
by Andrew Randrianasulu 13 Jul '20

13 Jul '20

I asked my russian-speaking friend to check it, but this may take some time... Please *do not merge* this version yet - new bugs may surface as we try to look at messages Attached modified .po file and compiled .mo file too. I used few first steps from HOW-TO.TXT 1) cd <path>/cinelerra-x.x.x 2) run xgettext: ./po/xlat.sh > po/cin.po then I moved cin.po and ru.po from /dev/shm/tmp/cinelerra-goodguy-20200711/cinelerra-5.1/po into my working directory /home/guest/Cin-translations after this I used msgmerge --output-file=ru-3.po ru-2.po ru.po msgmerge --output-file=ru-4.po ru-3.po cin.po msgfmt -c -o ru.mo.new-4 ru-4.po So many steps because I wanted to have backups in case I mismerge something ...

Mailing list & Gmail
by Sam 11 Jul '20

11 Jul '20

Hi Cinelerra friends, As some of you have already noticed, modifications to Mailman were necessary to get Gmail users back. To avoid spam, the major email providers use methods like SPF, DKIM and DMARC. We have adapted our mailing list so that the subject line and footer are no longer changed, i.e. the abbreviation [Cin] and the old familiar footer are missing. Thus DKIM is not broken and we are not classified as spam. We have also made other changes to meet modern requirements. Furthermore, only the mailing list address appears as the sender. We will gain more experience with the new procedures and if necessary we will make further optimizations. If you have any problems or other questions, please contact me. Sam

AOMedia AV1 2.0
by Andrew Randrianasulu 10 Jul '20

10 Jul '20

Hi all! Just was refreshing Phoronix page and this scrolls into view: https://www.phoronix.com/scan.php?page=news_item&px=AOMedia-libaom-2.0-Rele… --- AOMedia AV1 2.0 Codec Library Released With Many Improvements Written by Michael Larabel in Multimedia on 19 May 2020 at 06:53 AM EDT. 2 Comments MULTIMEDIA -- Version 2.0 of the libaom AOMedia AV1 video encoder / video codec SDK library is now available as the first major update in nearly two years. Libaom 2.0 is the first release since the original 1.0 release back in mid-2018 after the AOMedia codec working group approved the 1.0 release. The developers view this AOMedia AV1 2.0 release as now being their "first official release" for production. Libaom 2.0 adds a real-time encoding mode, SVC support, drops multi-resolution encoding, documentation updates, and other improvements to this open-source AV1 reference encoder. -- Hm, beaware about possible buildsystem changes, I guess? I have early snapshot running, from around Mar, 19 2020 but I have recent Cmake and stuff ....

Nest EDL
by Rafa Mar Multimedia en Gnu\Linux 10 Jul '20

10 Jul '20

Today I have been looking at nesting EDL, it seems like a wonderful function, but I have found a problem. Let me explain: When I open an .xml project in nested EDL mode, it loads in resources, very well, but if I open this EDL from there to make any changes, all the files of this project are loaded, which is very normal to occur this, so far so good, but when I close the EDL to return to the project, all the files get loaded, and this has puzzled me. I think the correct thing would be that when closing the EDL, only the files of this new project were left in the resources window. Or am I doing something wrong again? I have made a video so that what I quote is better understood. https://streamable.com/nn0lmf
